Hi All,

Which of these two gives more performance, Jumbo frames or TOE. Can
any one list out the advantages and disadvantages ot these two.

Thanks in advance.

That is sort of like asking - "Which is longer? A piece of red
string, or a piece of blue string?"

It depends - on how wimpy the processor in the TOE happens to be, or
if the TOE is based on an ASIC. And the sort of "performance" in
which you are interested - packets per second, or blinded by bits per
second.

An I/O card has some rather strong constraints on power - ISTR numbers
in the 20-30 watt per I/O slot range. That can put some non-trivial
constraints on the processing power available. Up in the host, the
host CPU(s) are O(100) Watts. Admittedly, one could write some rather
tight TOE firmware, or have an ASIC (knuth you with bugs found in
the field...)

JumboFrames more or less by definition has to be at both ends of the
connection, so there is an assist at both ends. TOE can be at either
the sender, the receiver, or both.

JumboFrames does little if anything if one is sending "small" (in this
context < ~1500 bytes) packets.

feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH...
